Exclude test/* from sdist

[sverhoeven]

When I build distros with python3 -m build I get a dist/grpc4bmi-0.4.0.tar.gz which contains the tests like test/test_client.py . The sdist should not contain test files.

The wheel does not contain any test files.

Tried automatic discover, but gave error:

error: Multiple top-level packages discovered in a flat-layout: ['cpp', 'data', 'proto', 'grpc4bmi'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.

Also tried exclude = ["test"] to pyproject.toml:tool.setuptools.packages.find , but test/** still included.

Might need to switch to src-layout or other build tool like hatch.

I tried some things, and it turns out that by including a MANIFEST.in file you can exclude the test folder.

MANIFEST.in

prune test

Was enough. It's automatically detected by setuptools.
